I'm trying to set in my Genexus project a "one time password" using the GAM and I'm following this and this pages on the wiki
I created the new authentication type
Set it as OTP for the local authentication type
Added the data for sending the mail (the same mail address is in all the three censored fields, an outlook mail)
And then I tell the user to use the 2FA, but I get this error (translated from italian, it could be slightly different)
"Failed to validate user in OTP custom event (GAM431)"
I can't find what I'm doing wrong. Am I missing a step? The user has a valid email address and the sending email address has the correct settings. What is missing?
